Capacitor-circuit board interface for welding system components

摘要

A welding system component includes a circuit board for the welding system component. An interface has a main riser portion with a fastener passageway formed therethrough. The interface has an extension portion with a terminal passageway formed therethrough. The extension portion is electrically connected to the circuit board with a terminal disposed in the terminal passageway. The extension portion is spaced away from a surface of the circuit board. A capacitor is electrically connected to the main riser portion with a fastener disposed in the fastener passageway.

主权项

1. A method of assembling a welding system component comprising:
providing a circuit board for a welding system component, providing an interface including a main riser portion extending generally orthogonally to a surface of the circuit board with a fastener passageway formed therethrough, and an extension portion extending generally parallel to the surface of the circuit board with a terminal passageway formed therethrough, providing at least one capacitor, electrically connecting the main riser portion to the at least one capacitor with a fastener disposed in the fastener passageway, electrically connecting the circuit board to the extension portion with a terminal disposed in the terminal passageway such that the extension portion is spaced away from a surface of the circuit board and from a surface of said at least one capacitor, said circuit board and said at least one capacitor in non-contacting physical relationship other than through said interface, the interface acting both as an electrically conductive path between said at least one capacitor and the circuit board and as a heat sink which reduces heat from the circuit board and the at least one capacitor as compared to when the at least one capacitor is directly connected to the circuit board.
